Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法,在不考慮燃燒的冷態情況下,研究了熱風爐燃燒室內的氣流分佈規律.在此基礎上,比較了2種不同設計方案的氣流流動特徵,尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和煤氣的流動和混合的影響.結果表明,阻流板的設計對加強空氣和煤氣的混合有著極為重要的作用,同時也增加了空氣管道的阻力損失,在同樣的工況條件下需要提高管道系統的總壓力Heat are recycled by a lot of suction holes arranged on the side of whole cooling section, hot gas are sucked through the holes, branch pipes, valves, and general pipes and then sent to dryer by suction fan
抽熱吸口,設于冷卻帶,熱風從不同的抽風口經由支管、閥門和熱風總管,由鍋爐引風機抽出送入乾燥,使之餘熱利用。The second chapter studies the economy of ship ' s power plants, based on the aspects of lowering fuel cost, waste heat recovery, the match of ship, machinery and propeller, increasing propulsion efficiency, increasing the economy of ship ' s power plants, etc. the third chapter discusses in detail the control measures of voyage change cost, analysizes systematically the voyage change cost based on the way of fuel cost, harbor cost, voyage venture cost. the fourth chapter studies the structures and control measures of seafarers cost, maintenance cost, spare parts and stores cost, lubricating oil cost, etc. which are relatively easy to be controlled ; based on the state maintenance decision - making, a mathematical model is put forward, the validity and its solve process are discussed. the control measures of spare parts, fuel cost and lubricating oil cost should be based on scientific budget, through the control means of application, reception, usage, store check, try to acquire the inosculation of theory
第一章主要討論營運船舶運輸成本,對船舶運輸成本的概念、結構、性質與分攤、成本細分進行了分析,從宏觀上闡明了船舶運輸成本的生存環境和生長趨勢;第二章研究了船舶動力裝置的經濟性,在營運船舶降低油耗、廢熱利用、船機槳匹配、提高推進效率、提高船舶動力裝置經濟性的有效途徑等方面進行了闡述和論證;第三章詳細論述並論證了航次變動成本的控制措施,全面系統地分析和總結了航次變動成本,通過對燃油成本、港口使費、航次風險成本的分析與控制,提出了航次風險成本的概念並論述了若干航次風險成本的控制措施;第四章對船舶營運成本中的船員費用控制、維修保養及其費用控制、船舶備件物料管理及其費用控制等幾個主要可控性較高的成本進行了細致的分析並分別討論了相互的控制措施,提出了基於狀態維修決策的馬爾可夫數學模型並論證了模型的正確性及具體解算步驟,對于備件、燃潤物料的控制堅持以科學的預算為前提,以申領、接收、使用、盤存為控制環節,切實做到理論與實踐的密切結合;第五章,結合營運成本的預核算的案例,對船舶營運成本的預算及核算進行了有益的探討,旨在揭示成本發生的動因,並給出了成本預算、核算的編制方法。In the region north of brazil, although both wind speed and air - sea humidity difference have dramatic variations, the variation of latent heat flux is just ordinary in magnitude. the reason is that the variations of wind speed and air - sea humidity difference are out of phase with each other so that they decrease each other greatly
在巴西以北的暖水區,盡管海氣濕度差的變化和風速的變化都較大,但二者在區域內總是反相,彼此削弱了對潛熱通量變化的貢獻,所以該區潛熱通量的變化振幅較小,最終由風速的變化主導潛熱通量的變化。The optimum inclination angle is between 15 ~ 20, the length of thermosyphon will not change the phase - change heat transfer coefficient of the evaporation section and the condensation, which will enlarge heat transfer area of thermosyphon and increase the heat exchange capacity. the head - on speed of wind only stranger the heat transfer of the evaporation section and the condensation section. the experiment shows that the mathematic model closely fits to the thermosyphon, moreover, the one key to resolve the thermosyphon effect lies in decreasing the thermoresistance of evaporating section and condensation section. this study can provide directions and experience in the future research
傾斜角越大,熱虹吸管總熱阻越大,最佳傾角在15 20之間;充液率過多或過少都會對傳熱性能產生不利影響,對于本實驗採用的1 . 75m 、 2m 、 2 . 5m 、 3m熱虹吸管,最佳充液率在20 % 35 %之間;管長對傳熱也有影響,管長不改變熱虹吸管蒸發段和冷凝段的換熱系數,只增加了熱虹吸管的換熱面積,增大換熱量;迎面風速的大小,起到強化熱虹吸管蒸發段和冷凝段換熱的目的。By analyzing the phenomenon of " rush " of port construction around china and the influence of the gap between port capacity and their actual throughput, from the need to further develop the theory of port construction, this paper puts forward the idea of establishing early warning management system to the investment risk of regional port projects from such aspects as the purpose, object, procedure and sigificance of the study
